Looking at the geo chart this is the most exciting open mold gravel release in quite some time -- great crossover potential as both an aero-oriented race bike for gravel or road or a winter training setup. Quite likely to bite the bullet on this!

To the 2by lovers: be aware that fitting 50mm wide tires (29x2.0) will cause problems with a front derailleur. In my case a eds tx front derailleur and race kings in 29x2.0 on elite wheels aero + rims with 30mm internal width. It just can't work because of the interference.
Even specialized pathfinder pros in 44c won't work on these rims as they build up to 46mm.
I'm pretty sad, as I bought the frame for riding 50mils with a 2by crankset.

A flyxii FE-02 will fit 53 WAM tires with 2x SRAM and even more clearance on GRX, where chainstays become the issue. Wicked cheap, too.

Whether you're competing in the TCR or your local 100k gravel fondo CdA gains in the frame benefits every rider, though I share the sentiment that "aero" on Chinertown is generally more of an aesthetic sensibility than the end result of rigorous R&D.

Just for fun, do you think this bike is more or less aero than a naked frame?


How about this one? Faster with or without the bottle?



Fender mounts, unused, are invisible to the wind and add a great deal of utility to the frame without adding any meaningful weight. Downtube mounts and frame storage allow for additional water carry behind the saddle — an aero gain — while preserving secure storage space for tools, tent poles, or yet more water. Because they effectively act as frame fairings or help stop airflow detaching, in many cases a bike equipped for bikepacking/ultraracing is _faster_ than one without.

Here you go;


A bike with mounts included for whatever you want to bolt to it is already available.
Maybe keep this one for a fast gravel frame with plenty of tyre clearance. 🤷‍♂️

Plenty of us bikepacking, ultraracing, or even just riding through winter benefit from the extra storage capacity. You add maybe 40g to an already 1000g+ frame by including some hidden fender mounts with an optional seat-stay bridge, ~15-20g for under downtube bolts. They're unnoticeable if unneeded and a massive increase to utility for those of us who do.

Agree that it looks like a G3 - they're likely just quoting clearance with the ISO standard of 4mm for road applications rather than the off-road standard of 6mm.

avoid the Winow stem, it's incredibly heavy and prone to slipping on the steerer. I'm happy with my Profile Design, it allows routing for Cervelo/3T style top tube entry points.

Can someone stuff a 55-56mm WAM tire in the front and let us know if it clears? If this can take a 2.2 in the fork it's probably the best option out there for people looking for a more aggressive Seigla

It looks like it's still a 1 1/8th steerer under the covers? Strange that they went from ~35mm WAM clearance on the 119 to this. 28mm is too small to clear a GP5K TT on 23 IW rims, so not sure I agree that it's "fine" - plenty of people will use these for long course or endurance cycling, and the extra width is certainly appreciated there.

Regardless, echoing Serge's comments: I was the TT119 guinea pig here, and I wouldn't buy another one.

I don't understand how this is a clone any more than every single round tube alu era bike was a clone of, idk, a CAAD3? The Aethos looks like every non-aero frame of the last 30 years and vice versa!

Hambini is EXACTLY the type of person I would expect to make something like that up.

It's fun to have a light, snappy bike that fills you with nostalgia for the period when you first started riding without all the downsides bikes from that era possess. Having a race bike with all the aero fixings is great for days where you need to go fast, but for the vast majority of rides -- even for very serious, competitive athletes -- marginal gains don't matter. On those days having a bike that makes you smile is worth infinitely more than 10w in a Tour test.

Aren't the black inc wheels an RD270-esque hub and commodity rim anyways? I say get some novelty logos on Wheelsfar or something from Peter.

In my infinite (lack of) wisdom, I did not pester Kitty about adding the plate they are shipping with the new HB052 to actually _mount_ these things to. Does anyone have a suggestion for brackets that might work and attach to the 25mm bolt spacing stackers that have come with the TT912 and TT119 previously? It looks closest to the Vision TFE/TFA extension adapters, but I don't believe those have the appropriate bolt spacing.

Totally depends on the seller/store which one are you referencing?

I'm referring to a legit Factor frame, not the copies. As weighed though and based on the previous posts, I would expect the high end v2 to be competitive.

Just saw a build thread on WW with weights listed for a sz 54 v2 in glossy black.

Frame was 927 including bottle bolts and both hangers, 476g for the fork. These frames really aren't far off...
